Komatsu introduces new semi-automatic excavator

Komatsu America has introduces its new PC390LCi-11 machine-controlled hydraulic excavator.

The company claims that it is the first 3D semi-automatic excavator available with the nimbleness and speed of the popular 36-ton weight class machines and stability of much larger machines.

“Whether it’s production excavating, utility trenching, site prep or any application where greater over-the-side lift capacity is required, this could be the machine operators fight over on the jobsite,” said Komatsu America product specialist Renee Kafka. “Also, to increase operator comfort and convenience, all PC390LCi-11 machines come standard with the machine-control-enhanced joysticks first introduced on the PC210LCi-11.”

The machine uses 3D design data loaded into the machine’s monitor to display the position relative to target grade. When the bucket reaches the target surface, automation kicks in to limit over excavation. ‘Intelligent machine control’  features a sensor package that includes stroke-sensing hydraulic cylinders, an IMU sensor, and GNSS antennas.

Features include:

Auto grade assist - as the operator moves the arm, the boom adjusts the bucket height automatically, tracing the target surface and minimizing digging too deep.

Auto stop control - during boom and bucket operation, the work equipment automatically stops when the bucket edge reaches the design surface, thus minimizing design surface damage.

Minimum distance control – the machine controls the bucket by automatically selecting the point on the bucket closest to the target surface. If the machine is not facing a sloped surface at a right angle, it will still follow the target surface and minimize digging below it.
